NCERT Exercises: Extracted Visible Questions with Solutions

Every visible NCERT question from the supplied screenshots is preserved with question number, wording, figure number and detailed solution. Figures 3.19 and 3.20 are recreated as responsive SVG diagrams.

Question 3.1: State, for each of the following physical quantities, if it is a scalar or a vector : volume, mass, speed, acceleration, density, number of moles, velocity, angular frequency, displacement, angular velocity.

Show Answer / Solution for NCERT Exercise 3.1

Detailed Solution:

Scalars: volume, mass, speed, density, number of moles, angular frequency.

Vectors: acceleration, velocity, displacement, angular velocity.

Exam Tip: Speed is scalar but velocity is vector. Angular velocity has direction by right-hand rule.

Question 3.2: Pick out the two scalar quantities in the following list : force, angular momentum, work, current, linear momentum, electric field, average velocity, magnetic moment, relative velocity.

Show Answer / Solution for NCERT Exercise 3.2

Detailed Solution:

Answer: work and current.

Reason: Work has magnitude only. Electric current is treated as scalar even though it has direction of flow in a circuit. Force, angular momentum, linear momentum, electric field, average velocity, magnetic moment and relative velocity are vectors.

Question 3.3: Pick out the only vector quantity in the following list : Temperature, pressure, impulse, time, power, total path length, energy, gravitational potential, coefficient of friction, charge.

Show Answer / Solution for NCERT Exercise 3.3

Detailed Solution:

Answer: impulse.

Reason: Impulse = change in momentum, so it has direction. All other listed quantities are scalars.

Question 3.4: State with reasons, whether the following algebraic operations with scalar and vector physical quantities are meaningful : (a) adding any two scalars, (b) adding a scalar to a vector of the same dimensions, (c) multiplying any vector by any scalar, (d) multiplying any two scalars, (e) adding any two vectors, (f) adding a component of a vector to the same vector.

Show Answer / Solution for NCERT Exercise 3.4

Detailed Solution:

(a) Meaningful only when the scalars represent the same physical kind. (b) Not meaningful because scalar and vector cannot be added. (c) Meaningful. It changes magnitude and possibly direction if the scalar is negative. (d) Meaningful. (e) Meaningful only for vectors of the same physical kind. (f) Not meaningful as written because a component is a scalar; a vector component along an axis can be added only after writing it as a vector.

Question 3.5: Read each statement below carefully and state, with reasons, if it is true or false : (a) The magnitude of a vector is always a scalar, (b) each component of a vector is always a scalar, (c) the total path length is always equal to the magnitude of the displacement vector of a particle, (d) the average speed of a particle (defined as total path length divided by the time taken to cover the path) is either greater or equal to the magnitude of average velocity of the particle over the same interval of time, (e) Three vectors not lying in a plane can never add up to give a null vector.

Show Answer / Solution for NCERT Exercise 3.5

Detailed Solution:

(a) True. Magnitude has no direction. (b) True. Rectangular component is a signed scalar. (c) False. Path length is generally greater than or equal to displacement magnitude. (d) True. Average speed = path length/time and magnitude of average velocity = displacement/time. (e) True. Three vectors adding to zero can be arranged as a triangle, so they must be coplanar.

Question 3.6: Establish the following vector inequalities geometrically or otherwise : (a) |a+b| ≤ |a| + |b| (b) |a+b| ≥ ||a| - |b|| (c) |a-b| ≤ |a| + |b| (d) |a-b| ≥ ||a| - |b|| When does the equality sign above apply?

Show Answer / Solution for NCERT Exercise 3.6

Detailed Solution:

Using triangle law, the third side of a triangle is less than or equal to the sum of the other two sides and greater than or equal to their difference. This gives (a) and (b) for a+b. Replace b by -b to get (c) and (d) for a-b.

Equality: Equality in the sum case occurs when vectors are parallel and in the same direction. Equality in the difference case occurs when vectors are parallel and opposite in the required arrangement.

Question 3.7: Given a + b + c + d = 0, which of the following statements are correct : (a) a, b, c, and d must each be a null vector, (b) The magnitude of (a + c) equals the magnitude of (b + d), (c) The magnitude of a can never be greater than the sum of the magnitudes of b, c, and d, (d) b + c must lie in the plane of a and d if a and d are not collinear, and in the line of a and d, if they are collinear ?

Show Answer / Solution for NCERT Exercise 3.7

Detailed Solution:

(a) Incorrect. Non-zero vectors can add to zero. (b) Correct. a+c = -(b+d), so magnitudes are equal. (c) Correct. a = -(b+c+d), so |a| ≤ |b|+|c|+|d|. (d) Correct. b+c = -(a+d), so it lies in the same plane as a and d; if a and d are collinear, it lies along that line.

Question 3.8: Three girls skating on a circular ice ground of radius 200 m start from a point P on the edge of the ground and reach a point Q diametrically opposite to P following different paths as shown in Fig. 3.19. What is the magnitude of the displacement vector for each ? For which girl is this equal to the actual length of path skate ?

Fig. 3.19

Show Answer / Solution for NCERT Exercise 3.8

Detailed Solution:

P and Q are diametrically opposite, so displacement magnitude = diameter = 2R = 2 × 200 = 400 m for all three girls.

The actual path length equals displacement only for the straight path B from P to Q.

Final Answer: Displacement for A, B and C = 400 m; path length equals displacement for girl B.

Question 3.9: A cyclist starts from the centre O of a circular park of radius 1 km, reaches the edge P of the park, then cycles along the circumference, and returns to the centre along QO as shown in Fig. 3.20. If the round trip takes 10 min, what is the (a) net displacement, (b) average velocity, and (c) average speed of the cyclist ?

Fig. 3.20

Show Answer / Solution for NCERT Exercise 3.9

Detailed Solution:

Total distance = OP + arc PQ + QO = 1 + (π/2) + 1 = 2 + π/2 km = 3.57 km.

Net displacement is zero because the cyclist returns to O. Average velocity = net displacement/time = 0.

Average speed = 3.57 km / 10 min = 0.357 km min^-1 = 21.4 km h^-1.

Question 3.10: On an open ground, a motorist follows a track that turns to his left by an angle of 60° after every 500 m. Starting from a given turn, specify the displacement of the motorist at the third, sixth and eighth turn. Compare the magnitude of the displacement with the total path length covered by the motorist in each case.

Vector diagram for 60° left turns

Show Answer / Solution for NCERT Exercise 3.10

Detailed Solution:

Each straight segment is 500 m and directions differ by 60°.

At third turn: resultant of three 500 m vectors at 0°, 60°, 120° has magnitude 1000 m. Path length = 1500 m.

At sixth turn: six sides of a regular hexagon close, so displacement = 0. Path length = 3000 m.

At eighth turn: after six turns displacement is zero; remaining two vectors at 0° and 60° give magnitude 500√3 = 866 m. Path length = 4000 m.

Question 3.11: A passenger arriving in a new town wishes to go from the station to a hotel located 10 km away on a straight road from the station. A dishonest cabman takes him along a circuitous path 23 km long and reaches the hotel in 28 min. What is (a) the average speed of the taxi, (b) the magnitude of average velocity ? Are the two equal ?

Show Answer / Solution for NCERT Exercise 3.11

Detailed Solution:

Time = 28 min = 28/60 h.

Average speed = total path/time = 23/(28/60) = 49.3 km h^-1.

Magnitude of average velocity = displacement/time = 10/(28/60) = 21.4 km h^-1.

Final Answer: They are not equal because path length is greater than displacement.

Question 3.12: The ceiling of a long hall is 25 m high. What is the maximum horizontal distance that a ball thrown with a speed of 40 m s^-1 can go without hitting the ceiling of the hall ?

Show Answer / Solution for NCERT Exercise 3.12

Detailed Solution:

For maximum horizontal distance without hitting ceiling, maximum height H = 25 m.

u_y² = 2gH = 2 × 9.8 × 25 = 490, so u_y = 22.14 m s^-1.

u_x = √(40² - 22.14²) = 33.32 m s^-1.

Time of flight = 2u_y/g = 4.52 s. Range = u_xT = 150.5 m.

Final Answer: approximately 150 m.

Question 3.13: A cricketer can throw a ball to a maximum horizontal distance of 100 m. How much high above the ground can the cricketer throw the same ball ?

Show Answer / Solution for NCERT Exercise 3.13

Detailed Solution:

Maximum range on level ground R_max = u²/g = 100 m.

Maximum vertical height with the same speed = u²/(2g) = R_max/2 = 50 m.

Final Answer: 50 m.

Question 3.14: A stone tied to the end of a string 80 cm long is whirled in a horizontal circle with a constant speed. If the stone makes 14 revolutions in 25 s, what is the magnitude and direction of acceleration of the stone ?

Show Answer / Solution for NCERT Exercise 3.14

Detailed Solution:

r = 80 cm = 0.80 m. Frequency f = 14/25 s^-1. Angular speed ω = 2πf = 2π × 14/25 = 3.52 rad s^-1.

Centripetal acceleration a = rω² = 0.80 × (3.52)² = 9.9 m s^-2.

Direction: horizontally toward the centre of the circular path.

Question 3.15: An aircraft executes a horizontal loop of radius 1.00 km with a steady speed of 900 km/h. Compare its centripetal acceleration with the acceleration due to gravity.

Show Answer / Solution for NCERT Exercise 3.15

Detailed Solution:

r = 1.00 km = 1000 m. v = 900 km h^-1 = 250 m s^-1.

a_c = v²/r = 250²/1000 = 62.5 m s^-2.

a_c/g = 62.5/9.8 = 6.38.

Final Answer: centripetal acceleration is about 6.4 g.

Question 3.16: Read each statement below carefully and state, with reasons, if it is true or false : (a) The net acceleration of a particle in circular motion is always along the radius of the circle towards the centre (b) The velocity vector of a particle at a point is always along the tangent to the path of the particle at that point (c) The acceleration vector of a particle in uniform circular motion averaged over one cycle is a null vector

Show Answer / Solution for NCERT Exercise 3.16

Detailed Solution:

(a) False. In non-uniform circular motion, tangential acceleration may also exist, so net acceleration need not be exactly radial. (b) True. Instantaneous velocity is tangent to the path. (c) True. Average acceleration over one full cycle is Δv/T = 0 because final velocity equals initial velocity.

Question 3.17: The position of a particle is given by r = 3.0t î - 2.0t² ĵ + 4.0 k̂ m where t is in seconds and the coefficients have the proper units for r to be in metres. (a) Find the v and a of the particle? (b) What is the magnitude and direction of velocity of the particle at t = 2.0 s ?

Show Answer / Solution for NCERT Exercise 3.17

Detailed Solution:

v = dr/dt = 3.0 î - 4.0t ĵ. a = dv/dt = -4.0 ĵ m s^-2.

At t = 2.0 s, v = 3 î - 8 ĵ m s^-1.

|v| = √(3² + 8²) = √73 = 8.54 m s^-1.

tan θ = -8/3, so direction is 69.4° below the +x-axis.

Question 3.18: A particle starts from the origin at t = 0 s with a velocity of 10.0 î m/s and moves in the x-y plane with a constant acceleration of (8.0 î + 2.0 ĵ) m s^-2. (a) At what time is the x-coordinate of the particle 16 m? What is the y-coordinate of the particle at that time? (b) What is the speed of the particle at the time ?

Show Answer / Solution for NCERT Exercise 3.18

Detailed Solution:

x = 10t + 1/2(8)t² = 10t + 4t². Put x = 16: 4t² + 10t - 16 = 0.

t = (-5 + √89)/4 = 1.11 s.

y = 1/2(2)t² = t² = 1.23 m.

v_x = 10 + 8t = 18.87 m s^-1, v_y = 2t = 2.22 m s^-1. Speed = √(18.87² + 2.22²) = 19.0 m s^-1.

Question 3.19: î and ĵ are unit vectors along x- and y- axis respectively. What is the magnitude and direction of the vectors î + ĵ, and î - ĵ ? What are the components of a vector A = 2 î + 3ĵ along the directions of î + ĵ and î - ĵ ? [You may use graphical method]

Show Answer / Solution for NCERT Exercise 3.19

Detailed Solution:

|î + ĵ| = √2, direction is 45° above +x-axis. |î - ĵ| = √2, direction is 45° below +x-axis.

Unit vector along î+ĵ is (î+ĵ)/√2. Component of A along it = A · (î+ĵ)/√2 = (2+3)/√2 = 5/√2.

Unit vector along î-ĵ is (î-ĵ)/√2. Component of A along it = A · (î-ĵ)/√2 = (2-3)/√2 = -1/√2.

Question 3.20: For any arbitrary motion in space, which of the following relations are true : (a) v_average = (1/2) [v(t₁) + v(t₂)] (b) v_average = [r(t₂) - r(t₁)] / (t₂ - t₁) (c) v(t) = v(0) + a t (d) r(t) = r(0) + v(0)t + (1/2) a t² (e) a_average = [v(t₂) - v(t₁)] / (t₂ - t₁) The 'average' stands for average of the quantity over the time interval t₁ to t₂)

Show Answer / Solution for NCERT Exercise 3.20

Detailed Solution:

(a) False. It is true only for constant acceleration. (b) True. This is the definition of average velocity. (c) False. It is true only for constant acceleration. (d) False. It is true only for constant acceleration. (e) True. This is the definition of average acceleration.

Question 3.21: Read each statement below carefully and state, with reasons and examples, if it is true or false : A scalar quantity is one that (a) is conserved in a process (b) can never take negative values (c) must be dimensionless (d) does not vary from one point to another in space (e) has the same value for observers with different orientations of axes.

Show Answer / Solution for NCERT Exercise 3.21

Detailed Solution:

(a) False. Scalars need not be conserved, for example kinetic energy may change. (b) False. Temperature in Celsius or electric potential may be negative. (c) False. Mass, time and energy have dimensions. (d) False. Temperature can vary from point to point. (e) True. A scalar is independent of orientation of coordinate axes.

Question 3.22: An aircraft is flying at a height of 3400 m above the ground. If the angle subtended at a ground observation point by the aircraft positions 10.0 s apart is 30°, what is the speed of the aircraft ?

Show Answer / Solution for NCERT Exercise 3.22

Detailed Solution:

For two positions at the same height h = 3400 m subtending angle 30° at the observer, distance travelled in 10 s is the chord/base: d = 2h tan(15°).

d = 2 × 3400 × tan15° = 1822 m.

Speed = d/t = 1822/10 = 182 m s^-1 = 656 km h^-1.

Final Answer: approximately 182 m s^-1.

NEET Focus

Memorise direct formulas: R, H, T, v = rω and a_c = v²/r.

JEE Focus

Use vector components, relative velocity triangles, trajectory equation and radius of curvature.

Graph Tip

Check what is held constant before selecting graph shape.

Final Check

Every numerical final answer needs magnitude, direction and units wherever applicable.
